He fetched with vigor and amped up the energy the longer we were together. Physically, he's remarkably clean and fit for a shelter dog with a shiny, short Brindle coat, clean ears, nice teeth and breath, bright eyes, etc. His body, legs and paws look GD while his tail and head look more GS. He doesn't really know how to walk properly, which is somewhat expected, and responded to some body language with jumping. Rex has been neutered, micro-chipped, vaccinated and comes with six weeks of free dog training classes. He's getting cat-tested [again] tomorrow at my request.

My Quandary:
I feel I have the space, experience, income and interest to take on Rex, but am unsure about how the German Shepard part of him may differ from what I'd expect from a Great Dane. My only exposure to German Shepherds has been limited to police and service dogs. This is a huge decision and commitment I'm facing. Taking on a brand new, pure bred Great Dane puppy would be more predictable than gambling on an 8-month old mixed breed who spent his first 6 months as a yard dog and the past 2 months as a shelter dog, with a 2 week foster care respite reportedly due to his increasing depression. This indicates his personality may be largely Great Dane since they are super sensitive. However, his intellect was exceptionally sharp, focused and quick. I had him sitting on voice command after maybe 3-4 physical instructions. As I sharpen my own training skills, I suspect he may be a very eager and adept student. But who knows?! Argh!! Should I visit him every day for the next week and see how we progress through 'Beginner' dog training lessons? (Katharina Schlegl-Kofler). I'm not worried about someone else adopting him since he's not moving now because of his size, energy level and jumping behavior.
I adopted an 8 month old (at the time) Great Dane-German Shepherd mix (Banner) in Dec '08, very recently. He has been a great dog so far, but some of your concerns are valid.
He definitely shows some amount of separation anxiety typical of danes, and also because he wasn't properly socialized as a young puppy some minor aggression (barking) towards strangers; mostly when we're out at night or in small spaces.
He is amazingly smart and eager to please, because he's not a young puppy we've had hardly any problems training him or with him chewing the "wrong" things.
Crate training was a must for us because of the separation anxiety, as well he sleeps in our room with us at night otherwise no one sleeps - we tried for a while with him downstairs.

I think that's all for now, if you have any other specific questions I can let you know how the mix plays out in Banner.
